this research was conducted on determination of better planting distance and better amount of nitrogen and phosphorus for hybrid rice (bahar 1). planting distance were used in this experiment, include 30×15, 30×20 and 30×25 cm as main factor. and also nitrogen fertilizer was used, include four levels, 65, 95, 125 and 155 k/ha and phosphorus fertilizer used include tow levels, 50 and 100 k/ha as...

objective: this field experiment was laid out in order to study on effect of nano and bio fertilizers on yield and yield components of tomato (lycopersicone sculentum l.) during the growing seasons 2013- 2014. methods: the experiment was laid out in a factorial based on randomized block design with three replications. treatments were k nanofertilizer in five levels such as (0, 100, 200, 300 and...

Farmer in different parts of Ethiopia uses a similar type fertilizer and amounts that are below the crop requirements, even low soil fertility which limits production general. To solve over-blanket application over agroecology Ethiopian Soil Information System (EthioSIS) mapped recommended types for specific location. A NPSB where Beko village, but rate this was not studied so far. So, field ex...

to assess the effects of different levels of nitrogen and phosphorous on yield and nutrient use efficiency of sugar beet (polygerm seed (cv. 7233)), this study was carried out in 1999-2001 in ardabil agricultural research station (alarough). the experiment contained two factors of: nitrogen in 4 levels (control, 100, 200 and 300 kg n/ha) and phosphorous in 3 levels (control, 100 and 200 kg p2o5...

proper application of n fertilizer and its optimization for increasing the economic yield of rice is definitely important. in order to determine the best n application method and amount according to growth stages of hybrid rice, an experiment was carried out at experimental farm of rrii in a factorial experiment based on a randomized complete block design with 3 replications. the treatments inc...

In this study the effect of four levels of nitrogen fertilizer (0, 50, 100, 150) kg/ha and four levels of super phosphate triple (0, 50, 100, 150) kg/ha were investigated on Rubia Inctorum L. (madder) under salinity stress. A factorial experiment was carried out in a research farm in Roaddasht, Isfahan based on complete randomized blocks with three replications. The results of the variance anal...

an experiment was conducted at assossa agricultural research center (aarc) station during 2008 cropping season in order to study the effects of co-inoculation of bradyrhizobium japonicum (tal-378 and tal-379) and phosphate-solubilizing bacteria (psb) (pseudomonas spp.), and conventional farmers’ fertilizer level (combined and individual application of 46n kg ha-1 and 46 p2o5 kg ha-1) on nodulat...
